How do I group an array of objects in JavaScript and sum a field?

import { groupBy } from ' groupjs_by ' ; const byStatus = groupBy ( orders , ' status ' ) . sum ( ' revenue ' , ' amount ' ) . count ( ' orders ' ) .

• Group a JavaScript array of objects using groupjsby's groupBy() function
• Sum a specific field (like revenue or amount) for each group based on a key (such as status)
• Install groupjsby via npm, handle zero dependencies, and skip null/undefined/non-numeric values
